HOLLOW FIREPROOF PARTITION SLIDING DOOR FOR FIlIRE-WALLS.

tion of Hollow Fireproof Partition Sliding Doors for Fire-\Valls, of which the following is a specification.

The object of my invention is to manufacture a door wholly out of sheet metal, without the use of solder, which shall have sufficient stifi'ness and rigidity to stand up under any ordinary strain, but which will allow at the same time, considerable expansion and contraction. My door, which may be made of any desired thickness, width or height, may be constructed as cheaply as the old fashioned wooden fire doors,- covered with tin which have heretofore been largely used and approved by the fire underwriters. My improved construction may be used equally well for shuttersior panel doors. I attain these objects by the construction illustrated in the accompanying drawings, in which all like numbers, or combinations of letters and numbers, designate the same subject in all figures.

Figure 1-is a front elevation. Fig. 2 is a vertical section on the line C D ot'v Fig. 1. Fig. 3 shows part of the side plate 1 of Fig. 1. Fig. 4: is a horizontal section 011 the line E F of Fig. 1. Fig. 5 is the top and bottom plate. Fig. 6 is a partial section on the line E F of Fig. 1. Fig 7 is the plate 12 of Fig. 6. Fig. 8 is an ornamental plate which covers the plate 12 of Fig. 6. Fig. 9 is a par- Fig. 10 is a part of the flanged sheet metal plate which. covers the edges of the upright sections atthe top and bottom. Fig. 11 isa larger View of part of the "plate shown in Fig. 5. Fig. 12 and Fig. 13 are angle irons used to fasten the top and bottom plates to the upright sections, shown also in Fig. 9, by 17 and 18. Fig. 14: is a vertical section of a corner of the door. Fig. 15 shows the same method of construction applied to a panel door.

1 of Fig. 1 shows an iron plate on each edge of the door. 2 is a plate similar to 1 on the top and bottom of the door. 3 is a piece of sheet metal with its edge turned down to finish the rough edge of the main body at the top and bottom. 4, a dotted line, shows how the top can be so desired. 5 shows a suitable hanger and rollers.

6 shows an opening in the connecting slide,

call connecting slides. 16 represents a rope to connect the fusible link and counterweight. i;- In Fig. 2, 5 shows a hanger and roller with an iron plate riveted on the inside of the body to bolt the hanger to. 10 is a fusible link. 15 shows a handle sunk in the opposite side, so as to leave one side of the door perfectly'smooth to fit close against the firewall when open or closed. I

InFig. 3 may be seen square, countersunk holes 14;, through which the rods 7 pass, and round countersunk holes. 13, through which pass the bolts to hold the plate to the angle iron as shown in Fig. 14:. i

As in Fig. 4,-represents asbestos packing,

- with which the door may be filled if desired,

though this is not necessary.

Fig. 5 shows top and bottom plates with countersunk round holes 13, for bolts to pass through. v I

Fig. 4, shows 19 spaces in door, divided by partitions, this making an uneven number of spaces and so making one space and one connecting slide with its holes and plates in the center of the door.

Fig. 6 shows a partial section online E F, Fig. 1, on a large scale to explain and show the construction of the spaces, of the main body and the connecting slides. The small letters in this figure designate the points where the sheet metal is to be bent, and-I shall now proceed to describe in what way these distances from letter to letter are to be bent, until the width of the sheet metal is used up. bc is turned in on cd, allowing room for 1"1 to slide. between. cd

is turned in square to d-6. 6- is. turned in tight on e-d. f-g is turned out on e-f, allowing room for s-t to slide in. g -k is turned in square to fg. h-i is turnedout square to h-g. z'k is turned in on vJ-h allowing room forl to 1 to slide in. kl is turned out on 71-h tight. Z- m is turned in on Z7c tight. mp s. is turned out on Z-m leavin room for another thickness of metal to sli e between. n0 is turned in square tOm-n. 0- is turned out square to no. H is turned out on 0-39, leaving room for w-w to slide in. g-r is turned out ti ht on These operations are .re-

peate until t e desired width of the door is square to l -l forming a shoulder against '12. 1-'1 is turned out square to 1' -1 and slides in space left between and 25-h, in the same way 1" slides in its proper place, and so 11 finishes the two endspaces. 11 represents connecting slides on both sides of the door to finish and close the spaces. 8 to t is turned out square tot'u and slides between f-e and f-g. M is' turned in square to forming a shoulder against e. 'u--'w is turned insquare to'u'w, forming a shoulder against g. 'w-a is turned out square to v-w and slides in' between 0 and p-g. The-distances as 1 to 1 k to d to e, u to '0, etc., can be increased or reduced so to obtain the exact width of door or shutter required, likewise the distances 0! to 1, h to g, n to 0, can be increased or reduced to gain the desired thickness of the door or shutter. 1

The third space in Fig. 6, shows the con struction of the center space and connecting slides in which 7 .shows a right and left threaded nut and rods. The rods pass through holes in. the partitions as through ll--f, hg, no, etc. The rods have, on the endlopposlte the thread, a round fiat head and next to it, a square shoulder to fit in square countersunk holes as shown in Figs.

'2 and 3. These rods are placed as often as necessary and hold the main body, the con necting slides and outside plate together, and can be loosened and tightened by the nut 7 through the hole 6 in the connectin slide with common gas pliers, but shoul never be ti htened too much so as to make allowance or expansion.

6 shows a hole in the connecting slide and inside plate shown by 12? which isriveted on the connecting slide'as shown by a. Fig. 7 showsthe same plate with a, the rivet holes, and 8, the boltholes, to bolt the ornamental stamped plate to cover the hole 6 after the rods are tightened. All necessary fittings as hangers, rollers, handles, fusible .link etc.', are applied according to the same principle, a-"plate riveted on the inside of the body with threaded holes to bolt the fit-' tin s-to. 1

ig. 8 shows the ornamental stamped plate to cover hole 6 as mentioned before.

17 and 18 of Fi 9 show angle irons, better' shown, 17 in ig. 12, and 18. in Fig. 13, with countersunk holes for rivets to fasten the-iron on the partition and threaded holes to receive bolts. All the holes are marked 13 and correspond in all the figures.

Fig. 14 shows how 17 and 18 are either riveted or bolted on the partitions of the door'or shutter, and the flanged sheet metal,

Fig. 10, and the late, Fig. 11, are fastened to the door by olts passing through the holes 13 into the threaded holes; 13 in Figs. 10 and 11 are to be 1 3' larger at least, 't-hanthe threaded holes of the angle irons, to allowflf or some expansion.

Fig. .10 shows a sheet metal strip with a flange turned down to finish and cover the sharp. edge on the top and bottom of the door'as mentioned before, and shown in Fig. 1,-and in Fig. 14 by 3.

spond with 13 of Fig. 10 andFig. 9.
